The durable, 50 UPF sun protection of Patagonia's Micro Swell Rashguard provides chafe free performance for marathon surf sessions, long downwinders or warm water dives. A lightweight, water friendly sun shirt made from a soft, stretchy 83% recycled nylon17% spandex blend, it features a modest crewneck and long sleeves for excellent protection from the sun while preventing board rash while paddling. Raglan sleeves with gussets keep seams away from sensitive areas and allow a full range of arm movement. Flatlock princess seams in front and back offer a comfortable, formfitting silhouette. Hip length for maximum coverage.
